UNITED STATES PATENT OFFICE.

OIL-CUP-CAP HOLDER.

Application med February 24,` 1927, serial No. 170,656.

The object of my device is to make a holder for the cap :t'or oil cups used in lubricating machinery. It is necessary to have a cap on the oil admission aperture of the cup. In filling the cup the cap must be removed. When the cup is filled the cap must be attached. In a great many instances the oil cup is secured to a movable part of a machine. In the conventional cap that is in threaded engagement with the cup, great losses have been incurred by the loss ot the caps. These caps are usually made of brass and are internally threaded and are only bought at a considerably high price even in large quantities. In the vibration of the cup the cap sometimes is loosened and falls olf or may even be lodged on a movable belt or pulley and injure persons adjacent the machine to which the oil cup is attached. In order to prevent the loss `of these caps and thereby also to prevent accidents, my cap securing` means is made.

Mydevice can be made of two pieces of wire properly bent, be made very .inexpensively, is easily applied to any conventional cup and may be likewise easily removed from any conventional cup.

lVith these and other objects in View, my invention has relation to certain novel features of construction and arrangement of parts as will be hereinafter more fully described. pointed out in the claim and illustratcd in the drawing in which,

Fig. l is a `front elevation of a conventional oil cup and cap with my device attached. rlhe cap in its removed position is slipwn by dashed lines.

Fig. 2 is a perspective view of my device and Fig. 3 is a front elevation of the cap of the oil cup, showing the groove into which aportion of my device fits. Numeral et designates a conventional oil cup having the cap 5, which cap 5 is in threaded engagement with the top of the oil cup over the oil entrance aperture. Numeral 6 designates an annular groove in the cap 5. Numeral 7 designates the connection between the oil cup and the machine to which it is attached.

My device consists of two pieces of `wire 8 and 9, the portion 8 being used for securing to the connection 7 and the portion 9 being used for a. connection with the cap 5. The piece Shas its lower end bent as shown at l0 into the form of a hook. The wire is suliiciently resilient that the hook l() may be forced over the connection 7 The piece 8 extends laterally from the hook 10 and then at substantially right angles to the plane of hook l() for a distance equal to the height of the oil cu proper. The upper end is then bent slight y inwardly and has the eye l1 formed at its upper end. The piece 9 passes through the eye 11 and is supported at its center. The material vis likewise resilient. The prongs l2 are bent arcuately opposite each other so that when the piece 9 is slipped into the annular groove G of i the cap 5, the cap is secured between the arcuate extensions of the prongs 12. The portion of the piece 9 between the eye 11 and the prongs 12 is bent at an acute angle from the plane of the prongs 12. It will be seen that when the cap 5 is unscrewed, and this unscrewing is made possible by the fact that the cap 5 can be turned between the prongs 12, it will assume the kposition shown in the Vdashed line in Fig. 1. Therefore, although the cap may be unscrewed, it cannot be lost because it will be held between the prongs l2 of the piece 9.

Vhat I claim and mean to secure by Letters Patent is:

device of the character described, comprislng two pieces or resilient wire, the end of one piece forming a hook, the other end of the same piece forming an eye, the two ends being joined by a portion of the piece extending laterally beyond and at right angles to the plane of the hook, the second piece extending through the eye of the first piece and having two prongs, each prong being bent outwardly in an arcuated manner opposite the other.

In testimony whereof I affix my signature.
